Nucleus: Functions: It contains hereditary information (genetic information, DNA) and It controls cell activity (cell functions) through DNA
Structure: This depends on weather cells are in state of division (Mitosis) or not (interphase) Interphase nucleus: Basic structure of the nucleus and Mitotic nucleus (in division)
Basic structure of the nucleus: Nuclear membrane: Is a covering formed by two membranes covered of ribosomes. It has pores that allow substances to be exchanged between the nucleus and the cytoplasm.
Nucleoplsm: Is the liquid in the nucleus Nucleolus: Is a rounded and dark structure where the components of the ribosomes are cgreated. Chromatin: Is made up of DNA filaments and proteins and contains genetic information. During cell division, it condense and forms chromosomes.
